It's very early days, but Leeds United could be forgiven for believing that they have another gem on their hands.
Academy graduate Ronaldo Vieira - signed professionally in May - has grabbed his promotion with both hands this summer, impressing in a number of pre-season games.
But the midfielder's performance in Saturday's 2-1 win over Atalanta has given rise to suggestions that he's the real deal, and Leeds' hierarchy should be wondering whether they should rip up the two-year contract he signed three months ago and replace it with a longer one.
By virtue of the fact 18-year-old Vieira started and managed 82 minutes in Leeds' biggest and toughest friendly of the summer, it might be fair to say that manager Garry Monk intends on showing him off in the Championship this season.
If he does, then Vieira - who received a standing ovation for his performance against the Serie A side - will attract much more attention, and Leeds would feel a lot better about his ever-rising profile if he was signed until, say, 2021 instead of 2018.
He has set the bar high after Saturday's showing, but he might well have the hunger, talent and ambition to maintain that standard for much of the upcoming season.
If he can - and it's not a big if, because Leeds will be facing lesser sides than Atalanta every week - then history might suggest Leeds will be powerless to keep him for long.
What they can control, however, is how much they lose him for, and a short-term contract makes them vulnerable to losing such a fine talent on the cheap.
Of course, he is at the very beginning of his senior career and tying him down for so long is a gamble, but early indications are that it's certainly a gamble worth taking.
